Bonnie & Bill - On the west side of Clermont there is a road - I forget the name, maybe cr19 that goes up past Cherry Lake Farms and then to the turnpike. Near where that road crosses Hwy 50 there is a small public ramp on the Palatakhaha River. Just across the ramp (almost) is a spot where you can jump out of the river banks into a smallish marsh. I've never ridden it but been fishing out there a lot and seen some airboats riding the area. That section of the Palatakhaha is limited by the bridge right there at the ramp, and a few miles down stream there is a flood control dam on the north side of Mascott. But inbetween there are 2 or 3 really nice lakes.
Please be careful with the sound levels. that area is EXPLODING with development, and you'd be boating in folk's backyards. It's not the best place, but the nearest. Probably not an issue on a nice saturday afternoon, but you DEFINITELY would not want to do any night riding out there.
You are invited to join us at Lake Kissimmee on April first. I believe the lake clean up event is based out of Camp mack, but there are several places you can trailer your boat to. If you need more info about directions, just ask.
There is a lot of marshy stuff down around Lake Louise State Park on the south side of Clermont. not sure if it's riding material though, and if it is, I'm not sure if airboats are permitted.
